Question 1

Suppose that a store decreases the price of laundry detergent from $4.1 to $3.5. As a result, quantity demanded increases from 210 to 240.

Using the mid-point elasticity approach, calculate price elasticity of demand.

Your answer should be expressed in absolute value terms.

 

Hint




Question 2

Suppose that a store decreases the price of cereal from $4.5 to $3.7. As a result, quantity demanded increases from 220 to 250.

Based on this information, find the price elasticity, which you can use to classify the demand curve as price elastic, unit elastic or inelastic.

 

Hint
